Specific implementation mode
In order to make the purpose , technical scheme and advantage of the present invention be clearer, with reference to the accompanying drawings and embodiments, right
The present invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and
It is not used in the restriction present invention.
The embodiment of the present invention, can after sensitive data file is transmitted by adding polar plot in sensitive data file
To be audited information according to the polar plot, file propagation person is traced, improves data security protecting ability.
Fig. 1 shows a kind of data security protection method provided in an embodiment of the present invention, and details are as follows：
In step S101, whether detection user is just in access sensitive data file, and when testing result is yes, then entrance walks
Rapid S102；When testing result is no, then flow restarts.
In embodiments of the present invention, sensitive data file be need to control propagate, the data file of circulation, can be for example, by
It is added to certain special tags in the data file, to show security sensitive.
Sensitive data rule is pre-defined, user accesses data is worked as by HOOK technologies as one embodiment of the invention
When file, judge to be accessed whether data are sensitive data by rule verification.
In embodiments of the present invention, access can be the operations such as to read, print.
In step s 102, polar plot is generated at random.
In embodiments of the present invention, polar plot is generated by Encryption Algorithm.
As one embodiment of the invention, the polar plot is the dot made an addition in sensitive data file white space.
It is using the advantage of dot, it is hidden enough, it is not easy to be found, after can preventing blabber from finding, be removed by technological means
It is propagated again after falling watermark, causes subsequently trace the problem of divulging a secret source.
As a preferred embodiment of the invention, the dot is multiple.Using the scheme of multiple dots, even if divulging a secret
Person has found one of them or several dot watermarks, and after being handled by technological means, as long as there is also it on the paper of printing
Remaining dot watermark, can trace back to immediate blabber.
As a preferred embodiment of the invention, the size of the dot is a pixel, and the dot of the size is enough
It is hidden, it is not easy to be found, and data exhibiting will not be blocked, avoid impacting user's vision so that office and reading are more
Add smooth.
In step s 103, the polar plot is made an addition to the white space of sensitive data file, and is recorded and the vector
Scheme corresponding audit information.
In embodiments of the present invention, the audit information includes active user's title, current sensitive data file and vector
Diagram data.
In embodiments of the present invention, the vector map data is for restoring polar plot and its position in sensitive data file
It sets, may include dot in X-axis and the coordinate ratio of Y-axis, the character accompanying by character and dot accompanying by dot
Several forward and backward character strings.
Due to vector map data contain the character accompanying by character and dot accompanying by dot it is forward and backward several
Character string, when can be to avoid a character of only dot corresponding attachment, query result might have repetition, and accuracy is not high
The problem of.
As a preferred embodiment of the invention, the number of above-mentioned character string is 5.
In embodiments of the present invention, the dot makes an addition to the lower left of corresponding character according to preset coordinate axis, can prevent from justifying
Point with underscore of the addition immediately below character, symbol or punctuate coincide emphatically, influence subsequent polar plot and detect.
As one embodiment of the invention, in practical applications, dot is attached to the position of header and footer in order to prevent,
When sensitive data file is A4 lateral lattice, added on A4 paper polar plot ranging from according to the ratio of A4 paper remove it is upper and lower,
In left and right 10% regional extent.
In step S104, file destination is obtained, and detects and whether there is polar plot in file destination, if testing result is
It is then to enter step S105, if testing result is no, flow terminates.
In step S105, polar plot generating algorithm is decrypted, obtains audit information, so as to be judged according to the audit information
It divulges a secret source.
In embodiments of the present invention, by adding polar plot in sensitive data file, and preservation and polar plot institute are right
The audit information answered, can be according to arrow after such as printing, taking pictures when the sensitive data file for being added to the quantity figure is illegally propagated
Spirogram obtains corresponding audit information can know the source of divulging a secret since audit information includes user's name.
The protection that sensitive data in operation system has been greatly reinforced by this method plays the printing operation of sensitive data
To the effect of tracking and monitoring, and controlling unit is introduced in operation system flow, has prevented sensitive data printing circulation way
Randomness, further, since the presence of watermark for business personnel sensitive data file each time operation all have deterrent
With it is traceable, so that data safety theory is goed deep into a line, the present invention has accomplished that the operation of sensitive data is controllable, to promote sensitive number
According to it is safe to use, even if sensitive data actively or passively divulge a secret, it is only necessary to find the polar plot got compromised on object
Position blabber for the first time so that the safety of sensitive data file greatly promotes.
As one embodiment of the invention, when tracing sensitive data file source, according to dot adhere to corresponding position with
And several character strings before and after dot, inquired in the audit information of system storage most matched as a result, judging to divulge a secret whereby
Source.
As a kind of preferred embodiment of the present invention, the quantity of the character string is 5.
As a preferred embodiment of the invention, the sensitive data file captured is analyzed by HOOK technologies, with picture
Element is that addition content is analyzed and spliced to unit, adheres to dot under the character of printing using the windows graphic interface GDI provided
The data volume of watermark, dot watermark is completed by page configuration at random with size, and dot watermark random printing is not changing user
In the case of custom, watermark addition is realized.
With reference to Fig. 2, by a specific print procedure, how explanation adds vector in sensitive data file
Figure, and data security protecting is carried out, details are as follows：
In step s 201, administrator enables strategy by WEB interface；
In step S202, background program Provisioning Policy is to client；
In step S203, client reception strategy；
In step S204, user executes printing；
In step S205, vector watermark strategy is judged whether, if so, S206 is thened follow the steps, if it is not, then executing
Step S207；
In step S206, printing content is obtained, watermark is generated according to algorithm and is added, and watermark identifier is uploaded to
From the background；
In step S207, printing.
